MACHINE FOR HEADING GRAIN.

laterally discharged grain from a harvester and binder with the binding devices removed, and head the grain thus received, discharging the stalks or straw in one direction and the grain heads in another direction.

A further object of my invention is to provide a simple and efficient apparatuswhich may be easily and freely adjusted,

even during the practical operation, so as to adapt the same to grain of diiferent lengths. With these and other objects in mind, my

invention resides in the apparatus shown in the accompanying drawings, in which:

Figure 1 is a plan view of my improvement; Fig. 2 is a transverse sectional view taken therethrough on the line 22 of Fig. 1, and looking forwardly; Fig. 3 is a vertical transverse sectional view taken through my improved apparatus substantially on the line 33 of Fig. 4: and looking rearwardly, the apparatus being shown as supported in connection with certain parts of the harvester and binder to be hereinafter specifically referred to; and, Fig. 4: is a sectional side elevation taken substantially on the line 4et of Fig. 3.

Referring now particularly to Figs. 3 and 4, A represents the main wheel frame of a combined harvester and binder, which as is well known, projects to one side of such machine and is supported by the main driv ing wheel (not shown), upwardly over which the cut grain is discharged by means of an inclined conveyer, the main wheel frame supporting a driven shaft A which is directly connected with the main wheel before mentioned, and which shaft is, in ac cordance with my invention, provided with a rigid sprocket wheel at intermediate its ends.

Specification of Letters Patent.

Serial No. 752,348.

My improved apparatus embodies front.

and rear upright walls B and B and an upright wall B intermediate the walls B and B and of reduced height, these three walls being spaced and connected by means of upper and lower bolts 7) and b respectively, of whichthe lower bolts I) extend loosely through parallel supporting beams C and C which are rigidly spaced and connected by bolts 0 and bolted adjacent one end to bridge pieces a supported upon and upstanding from the main wheel frame A and also bolted to a transverse bar a connected to side uprights a of the main wheel frame. Thus the walls B B and B which, with their connectionsconstitute the frame of my improved apparatus, may be readily adjusted forwardly and rearwardly with respect to the movement of the harvester in connection with which my improvements operate, so as to adjust the frame to properly receive grain of different lengths discharged thereinto from the inclined conveyer before mentioned, upon an inclined discharge plate A".

Journaled in superposed relation at the receiving side of my improved header, and extending between the front and rear walls B and B over the intermediate wall B are a pair of rollers D and D, each of which receives thereover the forward portion of its respective apron E or E, the rear portions of which are carried'by rollers D and D superposed in the opposite side of the frame and journaled in the wall B and the upwardly extending side portion 6 of the intermediate wall B As particularly indicated in Figs. 1 and a, the aprons E and E extend only between the walls B and B and between these aprons, of which the apron E is provided with transverse slats e, the stalks of the grain are conveyed, the heads of the grain extending rearwardly over the intermediate wall B Journaled through the lower portions of the walls B and B at the receiving side of the apparatus is the main shaft F, intermediately upon which is splined a sprocket wheel having an annularly grooved side piece f into the groove of which extends a yoke at the upper end of a supporting member F, the lower end. of which issecured to the supporting beam C. This sprocket wheel f is connected to the sprocket wheel a previously described, by a sprocket chain F and, by the supporting means just described, the said sprocket wheel f ismain-c tained in vertical alinement with the sprocket wheel a when the header frame is adjusted with respect to the supporting beams C and C.

At its forward end, the shaft F is provided with a sprocket wheel connected, by means of a sprocket chain F to a sprocket wheel mounted upon the forward end of the roller 19, this roller being connected to the roller D above the same, by means of intermeshing gears d and cl whereby to effect the rotation of these rollers and movement of the aprons E E". The shaft F is also provided with a sprocket wheel adjacent its rear end which is connected, by means of a sprocket chain G to a shaft G journaled through the walls B and B above and to one side of the shaft F, the shaft G being provided at its rear end with a crank disk g to the crank pin of which is connected the lower end of a pitman H, the upper end of which is connected to the lower end of the cutter bar H, this bar reciprocating verti'call-y in its cutter frame H? upon the rear surface of the upper portion of the wall B at an intermediate point. Thus through the connections stated, the cutter bar H is reciprocated' so as to cut off the heads of the grain carried sidewise through the frame, the stalks of which are moved between the aprons E and E and subsequently discharged laterally upon the inclined discharge plate I.

Secured to the'rear surface of the intermediate wal'l B and extending through the rear wall B is an inclined chute J, positioned below the cutter H and adapted to receive the grain bearing heads after they are cut, and to discharge the same into any suitable receptacle (not shown) which may be supported by other connections from the main wheel frame A of the harvester.

I claim:

1. The combination with a grain harvesting machine having horizontally projecting supporting beams, of a grain heading apparatus consisting of spaced upright walls, agrain conveyer operating horizontally between the upper portions of the walls, a' vertically reciprocatory cutter for removing the heads of the grain projecting at one side of the conveyer and a plurality of transverse bolts rigidly spacing and'connecting the several walls of the heading apparatus and loosely mounted through the supporting beams of the harvester whereby to permit of" adjustment of the heading apparatus for the purpose described.

2. The combination with a grain harvesting machine having horizontally projecting supporting beams, of a grain heading apparatus consisting of spaced upright walls,
